Throughout the several views of the drawings similar reference characters are employed to denote the same or similar parts.

As was noted above this invention pertains to improvements in knock-down boxes or cartons of the hollow wall type. Each of the modifications to be hereinafter described contain one or more hollow walls which is reinforced or strengthened both transversely and vertically thereof. As will later be apparent, with this basic thought, the foldable wall used therewith may be of contacting inner and outer wall members or spaced apart Wall members with the latter strengthened or reinforced vertically and horizontally or without such reinforcement as desired.

Specifically and referring to Figs. 1 to '1, inclusive, use is made of a blank cut or died and scored as illustrated in Fig. 1 with the blank comprising a bottom panel 25 bounded by score or fold lines 26, 21, 28 and 29. In the description hereinafter the score or fold lines 21 and 29 will be referred to' as the sides while the remaining score and fold lines 26 and 28 will be referred to as the ends, but it is to be understood that this terminology is used merely for purposes of convenience since the terms are interchangeable, the longer edges of a box being usually designated as the sides while the shorter is designated as the ends.

The base 25 has hingedly connected therewith through the score or fold lines 21 and 29 similar extensions 38 and 3| which in the erected carton form the side walls thereof. The base 25 has hingedly connected with its ends through the score or fold lines 26 and 28 similar extensions 32 and 33 which, again, in the erected carton form the. end walls thereof.

The side walls extensions 30 and 3| are substantially identical with one another wherefore it is deemed sufficient if but one of them, 3| for example, be described in detail to suifice for the both.. Accordingly, extension 3| is subdivided by a'plurality of score or fold lines 34, 35, 36, 31, 38, 39, 40 and 4| into panels 42, 43, 44, 45, 46, 41, 48, 49 and 50. It should be noted that the score or fold lines 34 to 4| inclusive are indicated by dash lines and this same system will be followed wherever score or fold lines are indicated while the solid lines will indicate cuts.

.In the erected carton the panel 42 forms the side wall outer wall member and has its ends defined by score or fold lines and 52. The panel 43 in the erected carton forms the side Wall top wall while the panel 44 forms the side wall inner wall member. The ends of the top wall panel 43 are defined by cut lines while the ends of the inner wall member 44 are defined by score or fold lines 53 and 54. The inner wall member panel 44 near its outermost corners, when extended as in Fig. 1 or near its lower innermost corners, when in the erected position, i provided with slits or narrow elongated apertures 55 and 56 which are utilized, as will later be made clear, to receive locking lugs from the carton end wall to hold the carton in erected positions. The remaining panels 45 to 56, inclusive, form in the erected carton the side wall bottom panel, side wall transverse braces, and glue flaps or side wall vertical braces. In practice glue or adhesive may be applied to the under side of panels 46 and 50, as seen in Fig. 1, and to the upper side of panel 48 again as seen in Fig. 1, but preferably the outer wall member or panel 42 is provided with spaced ribbons of adhesive as indicated at 51 and 58 and the adhesive 59 is applied to the upper surface of the panel 48. By applying the adhesive as just described each of the said adhesive ribbons is applied with the blank in the position illustrated in Fig. 1. The side wall vertical braces or glue flap panels 59, 48, and 46 each, respectively, have their ends defined by score or fold lines 68 and 6| forthe panel 50, 62 and 63, for the panel 48, and 64 and 65 for the panel 46. The side wall bottom wall member, and transverse brace panels 41 and 49 each have their ends cut and these cuts are in alignment with the score or fold lines for the various side wall panels as well as in line with the carton bottom or base end scores or fold lines 26 and 28.

The side wall outer wall member 42 through its ends scores or fold lines 5| and 52 has integrally hingedly connected therewith corner pieces 66 and 61 each of which corner pieces is respectively divided by a diagonal score or fold line 68 and 69. These corner pieces 66 and 61 form in the erected carton, a bellows corner.

Beyond the ends of the side wall panels transverse braces and glue flaps or panels are flaps or flanges subdivided by score or fold lines which are extensions of the score of fold lines 35 to 4|, inclusive, thereby providing in each flap or flange panels 18, 1|, 12, 13, 14, 15, 16 and 11 which are, in effect, extensions of panels 43 to 58, respectively. The flange or flap panels 18, 12, 14 and 16 are each spaced from its side wall extension panel by a rectangular opening while flap panels 1|, 13, 15 and 11 are each separated from its corresponding side wall extension panel by panels 82, 83, 84 and 85 whose outermost sides are defined by score or fold lines in alignment with the outermost edge of the openings 18 to 8|, inclusive. It should be noted that the width, that is the dimension running in the direction lengthwise of the side wall, of the panels 82 to 85, inclusive, and of the openings 18 to 8|, inclusive, is equal to the width of the end wall top wall member, as will later be made clear, and it should further be noted that the panels 82 to 85, inclusive, form hinges whereby the flap panels, after erection, may be swung to lie transversely of the base 25 and act as braces for the end walls.

The end wall extensions 32 and 33 are substantially duplicates of one another and it is deemed suificient if but one of them be described in detail for the both. Accordingly, extension 33 is provided with a plurality of score or fold lines 86, 81 and 88 subdividing the extension into panels 89, 90, 9| and 92 between the score or fold line 28 and the end of the extension.

In the erected carton the panel 89 constitutes the end wall outer wall member and has its ends defined by score or fold lines 93 which are in alignment with the base score or fold lines 21, and 29. The said score or fold lines 93 integrally hinged connect to the panel 89 the adja cent corner pieces 66 and 61. The panel 90, in the erected carton forms the end wall top wall ageee rea member while the panel 9! forms the" end wall inner "walr member? lengthequal thereto while the portion thereof adjacentithe panel 9| is of a length equal to said shorter panelwherefore the endsof the top'wall'panelfifl; beyond the-inner wall member Propanel st, is-contouredas at 94 and G5. jecting, from the 'sides of the panel 91, adjacent the outer ends thereof 'whenextending as in Fig: 1, andthe-inner loweren'ds-whenerected as in' Fig. 2; are: locking; lugs 96 and 91 which,

as intimated; entertheisi-de wall inner wall member slits 55* and56forlockingthe walls in erected position. In the erected carton the panel 92 acts-"as'aspacer for spacing the lower. end of the end wallinner-and outerwall member panels 89 and" fif'from "one another.

Afterthe blank has" been cut and scored as above'described the glue flap 50 along with the panel H 'atthe ends thereof are upwardly turned into: face contact with" the bracing panel" 59 whereupon theseipanels 'along with their end flanges panel. 16,. are then downwardly folded on the scoreor fold line iii-to bring the same-into face contact with the underside of the glue flap 48. The superimposed panels 59, 49 and 68 along with; panels 13-! and-46- arenow folded on the score or fold line'BT thereby bring glue panel iilinto engagement with the side wall inner wall member panel M for adhesively securingthe said glue panel' l8to the side wall inner wall member. The superimposed panels are now folded onthe score or fold line'35 thereby bringing' the glue flap 5!) and glue panel 46- into contact with'the'adhesive ribbons 51 and-58 for securing them to the inner face of side wall outer wall member panel. At this-time each of the sidewall. extensions 30 and 3| are; in" the folded and secured" position of the'extension 30 illustratedatthe top of. Fig: 1'. It. is-in this positionxthat the knock-down carton of the present invention is. shipped to the user. The folded andtglued .p'ositionsofthepartsare as illus-= tratediin cross section in.Fig: 3.

The user upondesiring: to; place merchandise tive position to' complete the carton and to look all ofthe walls "in their-operative relation to'o'nefanothen. Thesettingup'of the end walls is believed obvious, since; afterthe corner: pieces GB'jand'GT have been folded on'their diagonal scores or'fold lines 68 and'69, all that is required is that the various panels 89, 9B, 9! and 92 are to be folded to benormal to one another atwhich timethey willbelinthe positions illustrated in Fig. 6.

The raising'ofthe side walls from their flat positions: in Fig. 3 to their upstanding positions. in Fig; 2 aut'omaticallyarranged the top wall member. 1'3" and. bottom wall"member it'to be' parallel -to one *anotherandto the bottomwn 7a It will be noted that the-- end wallouter wall member panel 89 of a The connecting "top wall panel 90 hasthe'portion thereof adjacentthe panel 89 of a base 25. At the-same time the atransverse braces; 41 and 49 a where automatically" swungs. to; be; parallel with the top and bottom wall members:

and the bottom or'base 25 as seen clearly in: Fig. 4'. glue flap 50 are permanently secured to. the side walls inner and outer" wall members the transverse braces are retained: in their operative? positions. verse braces will resist any bending or 'displacement of either the inner or outer side wallmem bers' in either a direction toward the interior of the box or a direction outwardly thereof and at the same-time these transverse braces strength--- en the composite'wallsagainst bulging or other displacement. Since the side' transverse braces extend the full length of the said walls the same arebraced from end to end as clearlyillustrated in Fig; 7.

The tucking flap assemblies which includes the extension end flanges or flap panels 19 to 11 in--- elusive are folded relative to one another'at' the' same time that the side wall panels are folded and the said extension flange or flap panel" 15 is provided with adhesive 98 and is secured to the panel. H at the time that the side wall glue panel iB'is secured to the side "wall" inner-wall" member 44. It is therefore evident that" upon the setting up of the carton side" walls. from their fiat folded positionsiof'Fig. 3 to their'erected positions in Fig; 2 automatically sets'upthe tucking flap assemblies to the positionsillus trated at the lower end of Fig. '2. It will further be appreciated that the said tucking flap assemblies are provided with transverse braces which include the panels 16; 14, 12 andmr As seen in Fig. 6 the end wall inner and outer wall members 8% and 9! are transversely braced by the above identified composite tucking flap braces '58, 74, I2 and 10. These transverse braces resist movement,. or displacement of the end wall inner and outer wall members individually and as a unit.

Each of the side and end walls is. verti= cally. reinforced by the glue flaps and panels 59," 43 and 36 as well as the extension flange or'fiap panels thereof which are, respectively, 77, 15;.

and I3. I

By reference to Figs. 2, 4,.6,'.and 7' it will'be noted that. the .side and end wallsv are provided with cells between thetransverse braces and that.

with the blank of Fig. 1 there are three such cells; It may be desirable to increase or decrease the. number of cells and thereby the number of trans verse braces. Such a construction is illustrated in Figs; 8 and'9.

As illustrated in Fi 8 the blank has eliminated therefrom the glue panel 46 and transverse brace 41 and has the glue panel 48 integrally connected with the side wall bottom panel through the score'or fold line 31.

The processing of the modified'blank'of Fig." 8' is identical with that above described in connection with 'Fig; 1 and the setting up of the blank follows the same steps. The resulting boxor carton has substantiallythe same extension appearance as results from the blank of Fig. 1, the only difference being that the-side walls and end walls each have their respective inner and outer wall members braced by a single transversebrace instead of two such braces. The resulting side and end walls are again of cellular construction but have onlytwo cellsinstead of three. It will be readily apparent that by adding panels instead ofsubtractin'g panels from-'-t11e"-side"wai1"exten Since the glue panels 46 and48 and It will beobvious that the's-aidtrans-- 7 sions 3i and 32 a greater number of transverse braces may be provided. It may be noted that the number of such transverse braces depends upon the height of the carton walls and the use to which it is to be put as well as the goods to be packed and shipped therein.

In each of the foregoing modifications the box or carton has been provided with four walls each of hollow or spaced apart construction. It is sometimes desirable that the box or carton merely have two walls of the hollow or spaced apart construction with the remaining wall of appreciably less thickness, such for example as a double thickness. There is illustrated in Figs. 10 and 11 a modified blank to accomplish this result. Accordingly the blank of Fig. 10 has eliminated from its side wall extensions 38' and 3| the end flanges with the exception that the side wall outer wall member has integrally hingedly connected therewith through the score or folded line 53 a tucking flap 99. A further modification consists in eliminating from the side wall inner wall member panel 44 the slits or elongated apertures 5-5 and 58 substituting therefor a notch H03 in the outermost corner of said side Wall inner wall member M3.

The blank of Fig. is further modified in the end wall extensions 32 and 33 which as illustrated in Fig. 10, in the end wall extension 32' consists essentially of eliminating the end wall top wall panel 90 retaining the end wall outer wall panel 89, end wall inner wall panel 9!, and spacer panel 92 with said end wall inner and outer wall member panel 85 and st separated from one another by the score or fold line 56 and said imier wall member panel 8! and spacer panel 92 separated from one another by a score or fold line 88.

The side wall extensions 36' and 3! are illustrated as of the construction of modified blank of Fig. 8 but it is to be understood that they may be made as illustrated in Fig. 1 since the number of cells or transverse braces in the carton side walls may vary and still use the substantially thin or double material thickness end wall of Figs. 10 and 11.

The blank of Fig. 10 is folded, insofar as side wall extensions are concerned in substantially the same manner as the blanks of Figs. 1 and 8 and is shipped to the user in the folded knocked-down condition. The user in setting up the blank of Fig. 10, again, follows the same procedure as was followed in setting up the cartons in Figs. 2 and 9. The setting up of the carton of Fig. 11 requires the positioning of the tucking flaps 99 as the bellow corner pieces 86 and t1 transverse of the carton base or bottom 25 prior to the folding of the end Wall panels onto one another. The flaps 92 are modified blank of Fig. 10, instead of being positioned between the inner and outer wall members 89 and 9!, are arranged on the carton base or bottom to project into the carton and is a form of creeper as heretofore employed in boxes or cartons.

The boxes or cartons heretofore described pre sented the right or finished side of the paper or cardboard exteriorly of the side and end walls as Well as interiorly thereof, but presents to the user the wrong side of the paper or cardboard on the base or bottom. In some instances, such for example when it is desired to print on the sides and inner face of the base or bottom, it is desirable and necessary that the same or right side of the paper or cardboard to be presented to the observer on the inner and outer surfaces of the side and end walls as wellas on the upper g surface of the base or bottom. The carton or boxes illustrated in Figs. 12 to 20 inclusive are designated for this purpose and to have the Walls of reinforced or cellular construction.

One form of such carton is illustrated in Fig. 12 which, it will be observed, is quite similar to the blank of Fig. 8 since the resulting carton or box has but a single transverse brace. This blank, in so far as the side wall extensions are concerned, is modified over the blank of Fig. 8 to the extent that the panels or side walls outer wall members and top wall members as and 44 are made longer than the adjacent base or bottom bounding score or fold lines 27 and 29. The said panels 43 and M are increased in length the amount of the width of the panels 82 which constitute the spacing of the end wall inner and outer wall members and is occasioned by the fact that the end walls of Fig. 12 are folded from the inside out While the corresponding end walls of Fig. 8 are folded from the outside in.

The blank of Fig. 12 has the end wall extensions 32 and 33 modified over that in Fig. 8, one of which is illustrated in said Fig. 12 and indicated by the reference numeral 32", to the extent that the panel 355 is of less length than the panel EH since these panels respectively form the end wall inner and outer wall members instead of the end wall outer and inner wall members as do the panels in the said blank of Fig. 8. The panel 92' of the blank of Fig. 12 becomes the locking panel instead of a mere spacing panel as the corresponding panel 92 of Fig. 8 is employed.

The setting up of the blank of Fig. 12 is in effect rever ed to that of the blank of Fig. 8 since the panel 55 or glue flap is secured to the inner surface of the inner Wall member in such a manner that the bottom wall panel 45 is outwardly of the bounding score or fold lines 27 and 29 as illustrated clearly in Fig. 15. The glued up blank is shipped to the user with both side wall extensions in the position of the side wall extension 38 of Fig. 12.

The user upon desiring to set up the carton raised the said side walls to be normal to the base or bottom 25 whereupon the end wall extensions and tucking flap assemblies are in the positions of the near end of the particularly erected carton of Fig. 13. At this time the end walls are erected, in succession, by raising the end wall extension to be normal to the bottom 25 which disposes the end wall inner wall member or panel 39' in the position illustrated in Fig. 14 with the corner pieces 55 and 61 folded on themselves on their diagonal fold lines 69 and disposed transversely of the carton against the end wall inner wall member or panel 89'. This is illustrated in Fig. 14 in so far as one of the end wall corners is concerned.

The tucking assemblies are now arranged to V be transversely of the carton and to be placed in face contact with the folded corner pieces 66 and 67 again as illustrated in Fig. 14 in so far as one of said tucking flap assemblies is concerned. The end wal1 extension panels 9B, 9! and 92' are now folded to be normal to one another which disposes the panel or flap 52' against the lower surface or" the bottom or base 25.

In order to lock the walls in their erected positions the ends of the bottom wall panel at are left open for which purpose the score or fold line 371 at its extreme ends is changed to a cut or slit M32. This construction forms the ends of the side wall bottom wall into tabs or lugs beneath which the said panel or flap 92 has its corners inserted, as illustratedin Fig. 17, the said ends pr .,the..,side -wa1l bottom wall members, which eactnas .ilocking' tabs, .orllugsindicated by theref- ..erence numeral"! 03.

.The: foregoing description provided a carton or lboxlin which each of theside'walls as well as'the send walls. are of the spaced apartconstruction with a transverse "brace between said walls and .,'located intermediate the upper and lower ends ethereof. llnorder toprovidea cartonwith spaced 1apartorihollow sidewalls but merely double thick- ;ness-end walls ablanksuch as illustrated'in Fig. 18, may be. employed. This blank is'provided' with end wall. extensions, such asillustrated in Fig. 10, modified to the extent that thepanel 89" is less ,lengthfthan the panel 9 I since the panelfill" in Fig. ,18'forms the end wall inner wall member while the corresponding panelin'Fig. 10 forms the ,endwallouter wall member with the panels 9| and '9l" again reversing their positions in the ,erectedicarton.
